What is the relevance of magnetism to electricity?

Answer 1

Magnetism relates to electricity because they both have to do with moving charge.

Also if you have a magnet you can produce a current through induction and if you have a current, there is a magnetic field surrounding the current. So magnetism and electricity are somewhat intertwined.

Answer 2

An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.

If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops. The magnetic field can be strengthened even more by wrapping the wire around a core. The atoms of certain materials, such as iron, nickel and cobalt, each behave like tiny magnets. Normally, the atoms in something like a lump of iron point in random directions and the individual magnetic fields tend to cancel each other out. However, the magnetic field produced by the wire wrapped around the core can force some of the atoms within the core to point in one direction. All of their little magnetic fields add together, creating a stronger magnetic field.

As the current flowing around the core increases, the number of aligned atoms increases and the stronger the magnetic field becomes. At least, up to a point. Sooner or later, all of the atoms that can be aligned will be aligned. At this point, the magnet is said to be saturated and increasing the electric current flowing around the core no longer affects the magnetization of the core itself.

Answer 3

Magnetism is electrons (-) or protons (+) trying to become neutral by finding the small amount of each other. So in an magnet, one side has electrons and the other has protons, and they both attract different things.

Electricity, is basically movement of electrons. So its semi-related... But you can make magnets with electricity. Electro-magnets.

Answer 4

A moving current of electrons produces a magnetic field. The electric force and magnetic force are one in the same: The electromagnetic force.

Answer 5

Magnetism enables the use of electromagnets and the subsequent ability for a generator to produce electrical current but also for a motor to operate effectively.
